SPECIFICATION forming part of Letters' Patent No. 548,983,` datedOctober 29,1895. pplication filed August 4, v17894:. lSerial No.519,482.k (N ovmc'del.)

To a/ZZ whom t may concern:

Be it known that I, JOHNSON MAITLAND GROVER, publisher, of Winnipeg, inthe county of Selkirk, in the Province of Manitoba, Canada, haveinvented certain new vand useful Improvements in Washing-Machines, ofwhich the following is a specification;

My invention relates to improvements in washing-machines patented to mein Canada under No. 6,520 on the 7th of September, 1876; and the objectof the present invention is to provide a washer of simple and compactform,

in which the parts may be readily taken apart, if desired, and which maybe readily adjusted to suit the various sizes of tubs and in which theupper roller may be adjusted in relation tothe rubbing-frame accordingto the tension it is desired to exert upon such roller or the class ofclothes it is intended to wash; and it consists, essentially, in formingthe bearingstandards of the roller and rubbing-frame tubular, connectedtogether by a cross-bar and designed to be supported at one end by abracket in the tub and atthe other by a slotted arm extending outwardlyand held in position by a suitable thumb-screw screwed onto a bracketnear the top ofthe tub, a hand- Wheel being provided for rotating theroller, the springs being arranged at the bottom of the tubular frame topress against the reduced end of the rubbing-frame, and the machinebeing otherwise constructed as hereinafter more particularly explained.

Figure lis a perspective view of a washtub with a portion broken away,so as to exhibit the general arrangement and construction of mywashing-machine. Fig. 2 is a longitudinal section through the washer,showing, also, a wringing attachment. Fig. 3 is a cross-section throughthe line :n y, Fig. 2.

In the drawings like letters of reference in.- dicate correspondingparts in each figure.

A is the washtub, which is provided witha channel-bracket B, into whichfit the lugs c c' at one side of the frame O.- 'Y

C C2 are the tubular standards of the frame O, which are connectedtogether at the bottom by the cross-bar C3.

C4L is an arm extending outwardly from the tubular standard C2 andhaving a slot O5.

D is a bracket secured to the inside of the washtub and having a reducedupper threaded end d, which extends through-the slot C5 in the arm C4.

VD is a thumb-screw, which is screwed in the topof the endd and isdesigned to hold the arm rigidlyin position by pressing against the topof the arm C4. Y

It will be seen that on account 'of the length of the slot C5 in the armC4 the washer, may be readily adjusted to tubs of different sizes ordiameters. It will therefore be understood that each tub would have tobe provided with a bracket such as B and a bracket D.

E is the corrugated upper roller,which is provided at one end with around spindle e and at the other end with a spindle e', which is squareat its inner end, where it fits into the roller. The standards C C2 haveslots c2 c3, respectively, at the inside, which slots extend from nearthe bottom to the top of the stand# ard.

F F are cylindrical bearing-blocks, which iitinto the tubular standardsC' C2. The spindle e, at one end of the roller E, extends into thecylindrical bearing-block F,and the round end of the spindle c extendsthrough the cylindrical bearing-block F. The outer end ot' the spindle eis square and has secured toit the hand-wheel G, Which has a hole g madein the periphery and a hole g made through the Wheel near the riphery,into either of which may be inserted the vhandle g2. By means of thishand-Wheel G the roller E may be 'turned around by using the handle atthe side of the wheel or extending radially out from the periphery. y l

H is the rubbing-frame, and I the feed-rollers. The rubbing-frame H andfeed-rollersI are secured at each end in the crescent-shaped end boardsJ.

H. are pivot-pins extending out from the end boards through the slots c2and c3 into the tubular or hollow standards C C2.

K are spiral springs extending between the bottom of the standards C" C2and the pins H. By means of these springs K it will be seen that theframe H, with its feed-rollers, is maintained close up to thefeed-roller E in such a manner that such rubbing-frame and feed-rollersare permitted of a vertical movement in order to allow of clothes kofdif- IOO ferent classes, such as linen or light clothes or blanketsandheavy clothes, being readily put through the machine. In order to make afurther provision in this respect, I slot the cylindrical bearing-blocksF F at ff', as indicated in Figs. 2 and 3, and pass through such slotsfrom the outside of the hollow standards the screw-pnsfzfa, which Iprovide with thumb-nutsf4f5, the shank of each of which extends througha hole in the hollow standards, so that it may be screwed home againstthe cylindrical bearing-blocks, and thereby securely hold such bearingsin any position to which they may be vertically adj usted.

It will be noticed by reference to Figs. 2 and 3 that I make the upperportion of the blocks F of greater diameter than the lower and muchgreater height than I do in Fig. 1. In the first figure my machine issimply to be used as a washer, but in the last two figures I haveprovided a wringing attachment, which I shall now describe. L and M arethe wringing-rollers, which are made of any suitable material. The upperroller L is rigidly journaled in the top of the blocks F and F, one endbeing provided with a handle Z. The spindlesm of the roller M extendthrough the slots f6 and f7, made in the standards F and F',respectively.

N are rubber springs or cushions,upon which the spindles m of therollers M are supported. These cushions are designed to force the rollermont very convenient and ready for operation Y as part of my washer.

l From this description it will be seen that I provide a very simpleWasher, which, if any of the parts get out of order, may be readilytaken apart and repaired. It will also be understood that I am able touse springs K of more than usual strength, as I am enabled by thescrew-pins f2 and f3, extending through the slots f and f' in the blocksF and F', to provide any desired degree of pressure of the rubbing-frameII against the roller E.

The Washer may be very readily detached from the tub and removed to tubsof more or less diameter with very little trouble.

Vhat I claim as my invention is In combi-nation in a supporting framefor Washing and wringing rolls, the standards, the vertically movableblocks thereon having extensions above the upper ends of the standards,and having upper and lower bearings for the wringer and washing rollsrespectively, said blocks being slotted in the portions lying within thestandards and the laterally extending clamping means arranged to holdthe blocks in any adjusted position.
